[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] Existing open channel flow measurement poles are basically single poles with a cross arm, and radar flowmeters and other equipment are inserted into the center of the river for measurement. Alternatively, a flow measurement bridge is built to fix radar flowmeters and other equipment on the flow measurement bridge for measurement. The structure of a single pole with a cross arm for measurement is suitable for relatively narrow rivers. Once the maximum length of the cross arm is exceeded, this structure is no longer suitable for use. Although the flow measurement bridge structure can be applied to rivers of varying lengths, it is expensive, difficult to construct, and has strict requirements on the construction site. In addition, existing open channel flow measurement cables often use a single steel wire rope to fix the radar flowmeter, which is unstable and easily affects the accuracy of the measurement results.

[0009] According to a further technical solution, an annular steel wire rope is wound around the winding roller, and the rotation of the winding roller drives the annular steel wire rope to move.

[0010] According to a further technical solution, a second pulley and a third pulley are respectively provided on both sides of the winding roller, and a first winding plate and a second winding plate are respectively provided on both sides of the fifth pulley.

[0011] According to a further technical solution, the second pulley is connected to the first winding plate via a third steel wire rope, and the third pulley is connected to the second winding plate via a fourth steel wire rope.

[0012] According to a further technical solution, one end of the third steel wire rope passes over the second pulley and is fixedly connected to the counterweight, and the other end is fixedly connected to the first winding plate.

[0013] According to a further technical solution, one end of the fourth steel wire rope passes over the third pulley and is fixedly connected to the counterweight, and the other end is fixedly connected to the second winding plate.

[0016] Beneficial effects of the utility model:

[0017] The utility model adopts a double-side vertical pole structure of the river channel, is suitable for measuring the flow of rivers of different lengths, and has a low cost. The structure is easy to install and can be applied to single flow meters and array radar flow meters, etc.

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] See also Figure 1 , Figure 4 , Figure 6 As shown, an embodiment of the utility model provides an array-type radar open channel flow measurement cableway device, comprising a first upright pole 1 and a second upright pole 2 arranged side by side and at intervals, a first cross arm 5 and a second cross arm 6 are arranged above and below between the first upright pole 1 and the second upright pole 2, a first pulley 7 is fixedly arranged at the bottom of the first cross arm 5, and a winding roller 8 is fixedly arranged at the top of the second cross arm 6; the first upright pole 1 and the second upright pole 2 are fixedly arranged on one side of the open channel, a third upright pole 3 and a fourth upright pole 4 are fixedly arranged on the other side of the open channel, a third cross arm 11 and a fourth cross arm 12 are arranged above and below between the third upright pole 3 and the fourth upright pole 4, a fourth pulley 13 is fixedly arranged at the bottom of the third cross arm 11, and a fifth pulley 14 is fixedly arranged at the top of the fourth cross arm 12 and relatively to the fourth pulley 13; an annular steel wire rope 23 is arranged around the first pulley 7, the winding roller 8, the fourth pulley 13 and the fifth pulley 14, and a flow meter trolley 29 is movably arranged on the lower rope of the annular steel wire rope 23.

[0032] In this embodiment, if Figure 1 , Figure 2 , Figure 3As shown, according to the preset spacing between the first vertical pole 1 and the second vertical pole 2, the third vertical pole 3 and the fourth vertical pole 4, the ground cages 35 are respectively fixed at the corresponding positions on both sides of the river channel, and the ground cages 35 are fixed on the ground. Specifically, the double vertical poles adopt a double-sided piling structure, and the ground cages 35 include the first ground cage, the second ground cage and the third ground cage. The vertical poles are fixed on the first ground cage and the second ground cage, and the first ground cage and the second ground cage are connected by a steel plate. The third ground cage is fixed on the side of the first ground cage and the second ground cage away from the river channel, and the third ground cage is connected to the first ground cage and the second ground cage by a steel rolled strip. Such a ground cage structure greatly increases the stability of the flow measurement cableway device, reduces the construction difficulty, and reduces the cost.

[0033] After the cage is fixedly installed at the corresponding position, the first vertical pole 1 and the second vertical pole 2 are fixed above the first cage and the second cage. Figure 3 As shown, the first cage and the second cage are fixedly connected to the third cage respectively. Figure 3 The structures of the first cage, the second cage and the third cage are simply illustrated to clearly show other structures. It is only for illustration. That is, one side of the third upright pole 3 and the fourth upright pole 4 is the same as one side of the first upright pole 1 and the second upright pole 2, and the two sides are symmetrical. The third upright pole 3 and the fourth upright pole 4 are fixed above the first cage and the second cage, and the first cage and the second cage are fixedly connected to the third cage respectively.

[0034] The first vertical pole 1, the second vertical pole 2, the third vertical pole 3 and the fourth vertical pole 4 are all octagonal poles with reduced diameters, which reduce the cost while maintaining the stability of the structure, and are fixed to the ground cage 35 through flanges. Specifically, the bottom of the octagonal pole is vertically welded to the flange, and the flange is fixed to the ground cage 35 with double nuts to ensure that the nuts will not fall off.

[0035] In this embodiment, if Figure 3 , Figure 4 , Figure 6 As shown, the sixth pulley 17, the seventh pulley 18, the eighth pulley 19 and the ninth pulley 20 are fixed on the top of the first vertical pole 1, the second vertical pole 2, the third vertical pole 3 and the fourth vertical pole 4 respectively, and a lightning rod 30 is fixed on one side of the sixth, seventh, eighth and ninth pulleys.

[0036] In some embodiments, the lightning rod is made of galvanized material, which has a good lightning protection effect.

[0037] like Figure 1 , Figure 3As shown, the first vertical pole 1 and the third vertical pole 3 opposite to it are connected by the first steel wire rope 21 at the top of both, one end of the first steel wire rope 21 passes around the sixth pulley 17 and is connected to the bottom of the first vertical pole 1, and the other end passes around the eighth pulley 19 and is connected to the bottom of the third vertical pole 3; the second vertical pole 2 and the fourth vertical pole 4 opposite to it are connected by the second steel wire rope at the top of both, one end of the second steel wire rope passes around the seventh pulley 18 and is connected to the bottom of the third vertical pole 3, and the other end passes around the ninth pulley 20 and is connected to the bottom of the fourth vertical pole 4.

[0038] Both ends of the first steel wire rope 21 and the second steel wire rope 22 are provided with a rope tightener 32. The steel wire ropes on the same horizontal line must be kept in the same vertical position by tightening the rope tighteners 32 on both sides. Specifically, the steel wire rope is cut from the middle, one end of the cut is connected to one end of the rope tightener, and the other end of the cut is connected to the other end of the rope tightener, and the rope tightener is rotated to tighten the steel wire rope.

[0039] Through the above technical scheme, the first vertical pole 1 and the third vertical pole 3, the second vertical pole 2 and the fourth vertical pole 4 which are arranged opposite to each other on both sides of the river channel are connected by the first steel wire rope 21 and the second steel wire rope. Because the river channel is too long, the lightning rod 30 on the vertical pole cannot protect the equipment. The tops of the vertical poles on both sides are connected with two steel wire ropes and connected to the bottoms of the vertical poles, which plays a role in lightning protection. The two cross-over steel wire ropes can just prevent the equipment from being struck by lightning.

[0040] In this embodiment, if Figure 4 , Figure 5 As shown, a first cross arm 5 is fixedly provided between the first vertical pole 1 and the second vertical pole 2 and near the top, and a second cross arm 6 is fixedly provided at a certain distance below the first cross arm 5; a first pulley 7 is fixedly provided at the middle position of the bottom of the first cross arm 5, a winding roller 8 is fixedly provided at the top of the second cross arm 6 and at a position opposite to the first pulley 7, and a second pulley 9 and a third pulley 10 are respectively provided at the top of the second cross arm 6 on both sides of the winding roller 8.

[0041] The winding roller 8 includes a bracket and a winding shaft rotatably arranged inside the bracket, the bracket is a concave structure, the winding shaft is embedded in the bracket groove, a handle is provided on the side wall of the bracket, and the handle passes through the side wall of the bracket and is fixedly connected to the winding shaft. The winding roller 8 is fixedly arranged on the top of the second cross arm 6 through the bracket.

[0042] like Figure 6As shown, a third cross arm 11 is fixedly provided between the third vertical pole 3 and the fourth vertical pole 4 and near the top, and a fourth cross arm 12 is fixedly provided at a certain distance below the third cross arm 11; a fourth pulley 13 is fixedly provided at the middle position at the bottom of the third cross arm 11, and a fifth pulley 14 is fixedly provided at the top of the fourth cross arm 12 and at a position opposite to the fourth pulley 13, and a first winding plate 15 and a second winding plate 16 are respectively provided on both sides of the fifth pulley 14; an annular steel wire rope 23 is wound around the first pulley 7, the winding roller 8, the fourth pulley 13 and the fifth pulley 14, and the annular steel wire rope 23 can be moved by rotating the winding roller 8.

[0043] In some embodiments, the first cross arm 5 and the third cross arm 11, and the second cross arm 6 and the fourth cross arm 12 are horizontally arranged, and are spaced apart from each other by a river channel.

[0044] like Figure 1 , Figure 3 As shown, the second pulley 9 is connected to the first winding plate 15 via a third steel wire rope 24, one end of the third steel wire rope 24 passes around the second pulley 9 and is fixedly connected to the counterweight 34, and the other end is fixedly connected to the first winding plate 15; the third pulley 10 is connected to the second winding plate 16 via a fourth steel wire rope 25, one end of the fourth steel wire rope 25 passes around the third pulley 10 and is fixedly connected to the counterweight 34, and the other end is fixedly connected to the second winding plate 16.

[0045] In some embodiments, each of the pulleys is a fixed pulley.

[0046] The counterweight 34 provides a tensile force to the third steel wire rope 24 and the fourth steel wire rope 25 under the action of gravity. In winter and summer, due to the thermal expansion and contraction of the steel wire rope, the steel wire rope needs to be adjusted on site. This embodiment adopts a counterweight stretching method, which does not require on-site adjustment. The counterweight stretching structure greatly reduces the workload compared to the fixed structure. In order to keep the steel wire rope taut, the fixed structure will relax the steel wire rope in the summer due to the high temperature, and it is necessary to go to the site to tighten it again. The counterweight stretching method will keep the steel wire rope taut regardless of whether the steel wire rope is tightened or extended, and no on-site adjustment is required.

[0047] like Figure 2 As shown, in this embodiment, a flow meter trolley is movably arranged on the lower rope of the circular steel wire rope 23, and lock buckles 26 are fixedly arranged on both sides of the top of the flow meter trolley, which are used to fix the flow meter trolley on the circular steel wire rope 23 to ensure that the flow meter trolley will not fall off. Wheels are fixedly arranged at the four corners of the bottom of the flow meter trolley, and the wheels on one side of the flow meter trolley are rotatably arranged on the third steel wire rope 24, and the wheels on the other side are rotatably arranged on the fourth steel wire rope 25, which play a supporting role on both sides of the trolley, and are used to stabilize the flow meter trolley, so that the flow meter on it can receive data smoothly.

[0048] like Figure 7 As shown, a radar flowmeter 28 is fixed inside the flowmeter trolley 29, and a threading hole 27 is provided at the top center of the flowmeter trolley 29 for the cable to pass through. A chassis is provided on the maintenance platform, and a power supply and a data acquisition device are provided in the chassis. The radar flowmeter is connected to the power supply in the chassis through a power cable, and is connected to the data acquisition device through a signal cable. The power cable and signal cable extending from the chassis pass through the threading hole 27 and are connected to the radar flowmeter 28.

[0049] In some embodiments, the power cord and signal line extending from the chassis are hung on the circular wire rope 23 through a hanging ring, and are connected to the radar flow meter 28 on the flow meter trolley 29 along the circular wire rope 23, so as to avoid clutter and interference of the cables and facilitate the movement of the cables with the movement of the flow trolley.

[0050] Through the above technical solution, the top of the flow meter trolley is fixed on the lower rope of the circular steel wire rope 23, and the two sides of the bottom are respectively rotatably set on the third steel wire rope 24 and the fourth steel wire rope 25. The circular steel wire rope 23 can be moved by rotating the winding roller 8, and then the winding roller 8 can be rotated by the handle to drive the flow meter trolley to move between the poles on both sides of the river. In other words, when the winding roller 8 is rotated, the radar flow meter trolley is driven to move back and forth above the river along the third steel wire rope 24 and the fourth steel wire rope 25.

[0051] In this embodiment, if Figure 1 , Figure 2 As shown, a maintenance platform 31 is mounted on the first vertical pole 1 and the second vertical pole 2. One side of the maintenance platform 31 is fixedly connected to the side wall of the first vertical pole 1, and the other side is fixedly connected to the side wall of the second vertical pole 2, to ensure the stability of the maintenance platform 31, to prevent shaking or tilting during maintenance, and to ensure the safety of the staff. Support frames are also provided between the bottom sides of the maintenance platform 31 and the first vertical pole 1 and the second vertical pole 2 to further increase the structural stability of the maintenance platform 31 and prevent it from being deformed or damaged due to excessive load or external force.

[0052] A solar bracket 33 is also fixed on one side of the maintenance platform 31 for installing solar panels. The solar bracket 33 is hung on the maintenance platform 31 in the form of a hook and fixed with bolts to prevent it from shaking or falling off. A chassis is fixed inside the maintenance platform 31, and the chassis is equipped with equipment required for the operation of the radar flowmeter, such as a power supply and a data acquisition device. The power supply is connected to the solar panel, and the solar energy output by the solar panel is charged to provide power for the radar flowmeter, thereby achieving stable operation of the radar flowmeter.

[0053] A ladder is also provided on the side of the first upright pole 1 away from the maintenance platform 31 , extending from bottom to top, so that the staff can easily reach and leave the maintenance platform 31 .

[0054] The maintenance platform 31 is arranged near the second cross arm 6, so as to facilitate maintenance operations on the flow meter trolley. The maintenance platform 31 adopts the existing structure, and the staff can perform maintenance and install equipment on the maintenance platform 31. When the staff needs to repair the radar flow meter, they only need to rotate the winding roller 8 to swing the radar flow meter trolley to the maintenance platform 31 for maintenance.

[0055] Working principle details:

[0056] Arrange the open channel flow measurement cableway device. First, install the cage according to the preset spacing between the first and second poles, the third and fourth poles, and fix each pole on the cage at the corresponding position. Then, install and fix the first and second cross arms between the first and second poles in sequence, and install and fix the corresponding pulleys and winding rollers on the first and second cross arms; install and fix the third and fourth cross arms between the third and fourth poles in sequence, and install and fix the corresponding pulleys on the third and fourth cross arms. Set up the first steel wire rope, the second steel wire rope, the circular steel wire rope, the third steel wire rope and the fourth steel wire rope accordingly, and secure the radar flow trolley on the circular steel wire rope, the third steel wire rope and the fourth steel wire rope. A radar flow meter is installed inside the radar flow meter trolley for measuring the flow of the river. The winding roller is turned to move the radar flow meter trolley to the corresponding position. The radar flow meter can measure the flow velocity of the river after power is turned on. Multiple radar flow meter carts can be set up according to actual needs, and the radar flow meter carts can be fixed at different positions above the river channel to measure the flow velocity.

[0057] By turning the winding roller, the radar flow meter trolley is driven to move back and forth along the circular wire rope, the third wire rope and the fourth wire rope. When the workers need to inspect the radar flow meter, they only need to turn the winding roller to rock the radar flow meter trolley to the maintenance platform for inspection.

[0058] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
